Research:

Biogeography of the U.S.-Mexico border and its dispersal barriers

BorderSppDiversity

The border fence and border anthropogenic landscapes represent serious challenges to dispersal for many animals. I used biogeographical patterns along the border to identify species potentially threatened by 1) potential extensive border barriers in the future and 2) current border barriers. I then identified regions rich in such potentially threatened species.

The figure at right shows levels of regional species richness in a sliding window (r = 50km) across the transboundary region. Only species found along the border are considered. Blue shows the locations of pedestrian fences. Dotted lines are representative species ranges potentially divided by border barriers

Estimating dispersal limitation in community assembly in tropical forest tree communities

I am working on developing statistical models to test the importance of dispersal limitation and environmental limitation as processes that structure tree communities.  I hope to use the BCI plot dataset and data that I will collect in secondary forests in Amazonian Brazil.

The effects of landscape structure on the movements of edge frugivores and seed rain

In eastern Amazonian rainforest fragments I am studying how spatial structure of vegetation affects the movement of avian frugivore species that forage at the edge of primary forests and in neighboring open habitats.  Seed input into secondary growth can be limiting to forest succession, and the spatial distribution of frugivore dispersers is likely correlated to the spatial distribution of the seeds they deposit.  This work is being conducted at the Fazenda São Marcos, near Aurora in the state of Pará.  Support for this project comes from the Brazil Center and the department of Ecology Evolution and Behavior at the University of Texas at Austin, and from Tarcísio Meira, owner of Fazenda São Marcos.
